This invention relates tov gasoline torches.V

An object of the invention is the provision of a compact unitary structure having a bar# rel forming the storage chamber for fuel i and a handle for supporting thev torch while in operation. y

A further obj'ectof the invention yis the provision of a torch having a centrally disposed barrel forming a storage chamberfor `l@ fuel with means at one end for atomizing the fuel while means is employed at the oppositeV end of the barrel for providing an intense flame.

' This invention will be best understood from 15 a. consideration of the followingdetailed description, in view of the accompanying drawing forming a part of the specication: nevertheless it is to'be Yunderstood that the invention is not confined to the disclosure, being susceptible 'of such changes and modi# icationsv which shall define no material departure' from the salient features of the invention asexpressed in the appended claims.

In the accompanying drawing: Figure 1 is a vertical longitudinal section of a torch constructed in accordance with the principles of my invention;

Figure 2 is a longitudinal side view of the l torch;

Figure 3 is a transverse vertical section, taken along the line 3-3 of Figure 1; Figure 4 is a transverse vertical section, taken along the line4-4 of Figure 1.

Referring more particularly to the drawing, designates acylindrical barrel providing a storage chamber for fuel, which has one end enclosed by means of a removable plug 11 and the other end closed by a removable head 12. v A tube 13 extends axially andlongitudinallythrough the barrel 10 and has one end, as shown at 14, threaded into a passage or mixing chamber 15 of the head 12. The op-` 'jposite end of the tube extends through the pug 11 and is threaded, at 16, into a burner 1 The burner is cylindrical in form and is provided with a diagonal slot 18 at one end -Which is adjacent to the connection between the tube 13 and the burner 17. Mounted on the outer open end'` 19 of the cylindrical".y

burner '17 is a flame regulator 20 whichhasaV reduced end provided 'with an opening 21, e throughwhich the iame is adapted to extend. y

A linger piece 22 is secured to the flame rege 55y ulator in'any approvedV manner for apply-"f2" ing a regulator tothelburner-l?. Anumber of different regulators may 'be yemployed inf' which the discharge orifices 21 are ofdiflerent' sizes in order to -varythe size of the flame; 60 I' Two means vareemployed forfilling the? storage tankr cylinder :210. When it is de` sired 'to fill the storage-tank 10 by'manual'* `means a plug 25vis removed from the opening' 26 formed in the head v12 and the-liquid is 65 poured' into the passage 27 inl the 1 head 12 n which is in communication with the barrel or' storage chamber 10: s Y -v s When the barrel or storage tankV 10 is filled directly from' a stationary tank, ailie'Xible 70':

hose-is'connected toa threaded nipple 28 lafter` the cap'29 has been removed. A-pipe 30-is connected directlywith the nipp`le23 and eX tends downwardly and terminates 'at31"a d' jacent the plug 11'so that when-liquidis 75 forced into the barrel 10 iit will be directed to the bottomy ofthe tank. yAs soon as the barrel' has been' filled, the flexible tubing; (not shown) is removed and the ca-p`29 is-then f replaced. l 80 A restrictedpassage"35f`is located VinA `,the

wall of the chamber 27`and`connec'ts the upper 4 end of the barrel 10 with a mixing chamber* 15th* This passage is controlled by means of a needle valve 36-operated bya handle 375.` 85 The valve is held-in place on the'head 12 byj means of a lthreaded sleeve 38 and albushing A vpoitlO connects the mixingchamber 15a withthe atmosphere at one side of-a restrictl 90 Y ed passagef inorder to' supply said mixingv chamber with a predetermined quantity of air.V Y Thev passage 65 4connects chamber `15 with 15a. YA second port 41 connects the atmosphere directly-'with the chamber 1,5. A tube 42 connects the'mixing'chamber 1 5l Awith a block 43 which carries a connection 44 adapted to vbe placed in communication vwith compressed air-with the pressure of the air 1 being between twenty-liveand one hundred 710.0. l Y i j compressed j chamber 15a from the tube 42.

compressed air passing through the mixing chamber 15a Afrom the nozzle'() provides an aspirating effect passage 35 into the mixing chamber 15, airis drawn through th passage 4:0 to said mixing. chamber. As the air and fuel` from the mixing chamber enter the burner 17, the mixture burner 17` and i of the barrel provided with ber in communication withV4 the barrel, the head having a mixing chamber, a
